we need to use it. vaccine in the refrigerator never prevents flu. >> who should be given highest priority? >> everyone in the united states older than 6 months of age is recommended to get influenza vaccine. we've had a variety of new influenza vaccines available, regular shot, nasal spray variety, one that is higher dose, gives a bigger punch to seniors and then there's one with a teeny tiny little needle that doesn't even go into the skin. no excuses anymore. >> what do you tell people who are reluctant? >> do it anyway. not only important for you, it's important for all those around you. so you don't bring flu home or to work and give it to your c co-workers or those whom you love at home. it's a great holiday present. get vaccinated. make sure everyone gets the same present and gets vaccinated also. >> that's a good message, doctor. what about the people who say they're not reluctant because they don't like shots but they've gotten sick, they say, in the past from the flu vaccine. >> heaven forbid.
